4 in. TRUE SCH-80 PVC Union Socket-Ends w/ EPDM O-Ring Seals ASTM D2467/F1970 Super Heavy-Duty

247Garden’s 4 in. TRUE Schedule 80 PVC Union Socket-Ends with EPDM O-Ring Seals are engineered for maximum strength, chemical resistance, and ease of maintenance in demanding industrial, agricultural, and commercial piping systems. Constructed from premium, corrosion-resistant PVC material that meets ASTM D2467 (PVC fittings) and ASTM F1970 (PVC pressure-rated socket-type fittings) standards, these unions provide reliable performance under both high-pressure and heavy-duty applications.

The TRUE SCH-80 designation ensures a thicker wall construction compared to standard Schedule 40, delivering superior burst strength and impact resistance while maintaining a smooth internal bore for optimal fluid flow. Each union features precision-machined socket ends for a secure solvent-weld connection to PVC piping, ensuring a leak-free seal and long service life.

An industrial-grade EPDM O-ring is seated within the union body to deliver a tight, resilient seal that stands up to a wide range of chemicals, acids, alkalis, and water-based solutions. This elastomer choice offers excellent flexibility, weather resistance, and temperature tolerance, making it ideal for irrigation, water treatment, aquaculture, chemical handling, and other high-demand environments.

The three-piece union design allows for quick disassembly and reassembly of piping sections without cutting the pipe, making it easy to clean, inspect, or replace system components while minimizing downtime. The robust super heavy-duty construction resists deformation under pressure and repeated assembly cycles, ensuring reliability in both static and dynamic applications.
